Occipito-cervical junction This disorder may result from rheumatoid arthritis, causing the hypermobility of the connection between the neck and head, resulting in paralysis or pain. [6] Cerebrovascular disease Cerebrovascular disease is a type of cervical spine disorder that can cause tetraplegia. [7] Subaxial cervical spine [8] Atlanto-axial joint
It represents <1% of all cervical spine injuries. [1] Several subtypes of atlanto-occipital dislocation are known. One suggested categorization scheme includes anterior, vertical and posterior of the head relative to the spine. Other variants with lateral or rotatory displacement have been described, as well as mixed types.
Cervical spinal nerve C7 controls triceps and wrist extension. Cervical spinal nerve C8 helps control the hand. [18] The cervicocranial syndrome occurs when symptoms arise due to cervical vertebrae damage (misalignment, collapse, shift or disease, such as tumor) resulting in the improper functioning of the cervical spinal nerves.
Ansa cervicalis. The superior root of the ansa cervicalis (formerly known as descendens hypoglossi [1]: 500 ) is by fibres of the cervical spinal nerve 1 [1]: 344 [3] (and, according to some sources, of cervical spinal nerve 2 as well [3]) that have joined and run with the hypoglossal nerve (CN XII) for some distance before [1]: 344 progressively [1]: 369 branching off the CN XII in the ...
In anatomy, the axis (from Latin axis, "axle") is the second cervical vertebra (C2) of the spine, immediately inferior to the atlas, upon which the head rests. The spinal cord passes through the axis. The defining feature of the axis is its strong bony protrusion known as the dens, which rises from the superior aspect of the bone.
The three categories treated for types of spinal cord deficiencies are massive fusion of the cervical spine (Type I), the fusion of 1 or 2 vertebrae (Type II), and the presence of thoracic and lumbar spine anomalies in association with type I or type II Klippel–Feil syndrome (Type III).

Cervical Spondylotic Myelopathy (CSM) is a disorder characterised by the age-related deterioration of the cervical spinal cord. [1] Referred to be a range of different but related terms, a global consensus process selected Degenerative Cervical Myelopathy as the new overarching disease term . [ 2 ]
However, the cervical spine is comparatively mobile, and some component of this movement is due to flexion and extension of the vertebral column itself. This movement between the atlas and occipital bone is often referred to as the "yes joint", owing to its nature of being able to move the head in an up-and-down fashion.
